## Development

Platforms supported as development environment include Linux (possibly
other POSIX systems) and Windows (with MSYS2 and CPython).

### Platform specific prerequisites

-   Archlinux:

        $ pacman -S $(< requirements.archlinux.txt)

-   Ubuntu:

        $ apt install $(< requirements.ubuntu.txt)

-   Windows:

        $ pacman -S $(< requirements.msys2.txt)

### Python prerequisites

    $ pip install -r requirements.pip.txt

### Build

Build tool used for Hat is pydoit ([http://pydoit.org/]{.title-ref}). It
is included as one of python prerequisites and should be available after
[pip]{.title-ref} requirements installation.

For listing available doit tasks, use:

    $ doit list

Default task:

    $ doit

creates [dist]{.title-ref} folder containing built packages.

### Documentation

Documentation can be built with:

    $ doit docs

which creates [build/docs]{.title-ref} folder containing documentation.

### Tests

Tests can be run with [doit]{.title-ref} task `test`.

-   Unit tests:

        $ doit test test_unit

-   System tests:

        $ doit test test_sys

-   Performance tests:

        $ doit test test_perf
